Effect of external vehicle perturbations on tactile perception by electrovibration

Navigating touchscreens in vehicles becomes increasingly challenging when subjected to external perturbations like air turbulence or bumpy roads. These perturbations can lead to a loss in task performance, reduced finger accuracy, and increased frustration among users. To address these issues, electrovibration has emerged as a promising...

User Exploratory Behaviour and Perception in Unconstrained Tactile Exploration Using Electrovibration

Electrovibration offers potential to enrich virtual touch experiences with authentic tactile sensations on touchscreens. In controlled environments, responses to tactile stimuli may be anticipated, yet this predictability becomes uncertain in unconstrained settings due to dynamic factors like varied applied force, finger scanning speed, and...

FeelPen: A Haptic Stylus Displaying Multimodal Texture Feels on Touchscreens

The ever-emerging mobile market induced a blooming interest in stylus-based interactions. Most state-of-the-art styluses either provide no haptic feedback or only deliver one type of sensation, such as vibration or skin stretch. Improving these devices with display abilities of a palette of tactile feels can pave the way for rendering...

FeelPen: A Handheld Multimodal Haptic Interface for Displaying Augmented Texture Feels on Touchscreens

The ever-emerging mobile market induced a blooming interest in stylus-based interactions. However, most state-of-the-art styli are passive or display only unimodal tactile feedback. Multimodal haptic devices that simultaneously stimulate our cutaneous and kinesthetic receptors to provide immersive and realistic sensations in a virtual...

Finger motion and contact by a second finger influence the tactile perception of electrovibration

Electrovibration holds great potential for creating vivid and realistic haptic sensations on touchscreens. Ideally, a designer should be able to control what users feel independent of the number of fingers they use, the movements they make, and how hard they press. We sought to understand the perception and physics of such interactions by...
